7' Claims.

The present invention relates to improved methods of making, packing and sealing cartridge containers. These containers fabricated from paper or cellulose materials-such types of receptacles particularly though not exclusively, cylindrical in form and especially those adapted to be used for packaging of foods and more especially foods having dehydrated characteristics.

The primary object of the present invention is to provide a simple, effective, and economical method for. making, packing, and sealing containers of this type.

A further'object-of the invention is to make, charge and seal such containers with substantially no waste of materials in the operation of the same.

for outer or inner closures, flanged or unflanged,

blanks.

Figure 7 is a top plan-view of Figure 6. I Reference now being had to the numerals the headblock l is vertically movable in its guides 2; fixed to the guides are right and left crimping .means 3. These are stationary and held by yokes Reference being, made to the accompanying .drawings describing the invention, attention is directed to the copending applications Serial No. 449,949, filed July 6, .1942, and also Serial No. 472,640, filed January 16, 1943, the former is hereinafter referred to as the primary unit and the not shown. ;These crimping means are composed of cylindrical housings 4 and provided with a rotary broach 5 which has a taper end 6 and a rotary crimping roller 1 piercing and held by the broach for rotary movement. As the broach rotates, the roller rotates through friction hold upon the end of the tube to be crimped. At the opposite end of the broach is a screw member-8 having an enlarged portionprovided with ball or other anti-friction bearings 9, which is disposed between the taper end of the broach and the screw threaded portionof the same. ,An extension shank of the screw threaded portion. is

/ ii and as the screw threaded. portion 8 works within the housing 4 the requiredleverage to This consists of 'a broach 5 having a taper portion 3 at one'end thereof, a threaded shank 8 at the opposite end thereof; an enlarged portion or hearing .9, mounted for reciprocal movement inv a housing 4; the taper portion of the broach 3 adapted to rotate within the end of tubular bar, with yokes fixedto the headblock guides, to

prevent premature ejection of materials-within an aperture of the headblock.

Figure 3 is a fragment of an adapter stop, the adaptor being a sleeve of variable thickness in seei the aperture to compensate for different diameters of preformed tubing in the preparation .of the container tubes.

Figure 3A is a cross section of the vertical axis of'the bipartite headblock of the secondary unit,

for forming flanges on inner tube.

. Figure 4 is a fragmentary top plan view of Fig.

3A for forming flanges on the inner tube. Figure 5 is a view in elevation of one of the male dies, with the female die shown in dotted lines, supplementaryto Figure 3A.

1 Figure 6 is an end closure die for pressing or upsetting by deforming and making a flange 0n a-preformed disk for a spacingend closure. The

elements shown in Figure 5 with-modification in degree and not in kind may be used substanmaterial to be crimped; a spindle l pierces the broach and is mounted at right angles to the- I axis of'thebroach. The spindle I rotates with end of a tube, and by virtue of the geometrical shape of the tube, circular, and the taperof the broach, the inclinationof the end of the tube to bend inwardly owing toits geometrical form, is

furthered by the spindle grooves pressing upon the end in such a manner as to infold the end of theLtube-and against the taper portion of. the broach which irons or crimps the same inwardly. The crimping head, with the screw and broach rotateslupon its axis; and the spindle rotates with it in the same orbital or rotary movement. The spindle of the crimping means rotates in idling as above noted, but in addition thereto it rotates upon its own axis as wellv as the aforementioned. when in contact with the work.

Disposed within an aperture ofthe headblock' 7 to the secondary unit for the fianging operation of the ends of same which is more fully and hereinafter described.

- The ramrod l6, Fig. 1, registers with an aperture of the headblock when brought in registry therewith, and disposed in the said aperture at its greatest diameter is a piece of tubing H the outer tube which isheld from premature ejection by means of the slidably mountedshackle bar l8 carried by the yokes i9.

Disposed opp site to the adapter is apiece of tubing shown in section designated M andwithin the adapter a piece of tubing (cut off) I5, to be relayed to the secondary unit for deforming flanges thereon. Disposed within the piece of tubing H opposite the ramrod It is the deformed inner tube having flanges, known as the inner tube 22 also charged with product, and having end closures 20 and 2! at its ends ready to be moved upward to the crimping means and have the ends of the outer tube, ll folded inwardly and crimped thus sealing the encased elements and product therein contained.

The inner tube 22 is flanged or deformed on the secondary unit, asin Figures 3A, 4 and close upon tubes for the flanging operation, designated 22, the headblock 23 is shifted in guides coacting with shoes 24 by means of the pistons 25 and the male dies 26 with extensions 2'? deform the ends of the tube of the bipartite headblock whichis in effect the female die. In Figures 6 and 7, Figure 6 ayertical axis cross section of the bipartite headblock shows'the. headblock 23, the female die 28 carried by the bipartite headblock 23 in which the disc 30 is deformed by pressure from the male die 29 upon the disc 30 within the female die 28, thus forming a flange, by deformation of a flat disc. The ejector rod 3| is utilized to' eject the flanged disc 30 from the female die 28.

inner and outer tubes fabricated into inte'rfltting relationship are compensated bythe arrangement and dimensions of apertures in the headblock of the primary unit and in the dies carried by the bipartite headblock. Figure 3a discloses the male die' l3 cooperating with the plunger and female die I2 held by the: bipartite headblock for upsetting or deforming the ends of an open end piece-of tubing. In passing from the primary unit tothe secondary unit by way of the rotary conveyor, the ends of this 'piece of tubing ing peripheral flanges on closure disk members;

stuffing the flanged tubular member; pressing the filled tubular member into another tubular member; inserting the peripherally-flanged closure disks; inserting other closure disks thereover' and crimping the ends of the second tubular member over the second closure disks, substan-:

tially as described.

2. The method of fabricating insulated cartridge containers; forming circumferential Y flanges on the ends of a tubular member; formthe bipartite headblock 23 is composed of right and left sections laterally shiftable to open and The tolerance of difference in diameters of the to be deformed are wetted in hot paraffin, this end closures, it may be also used wtih substantially heavy stock for this purpose and as such wetted surface does not comeinto contact with the contents nor has any intercommunication ing peripheral flanges on closure disk members;
